How many options does a mailer have for the placement of an ancillary service endorsement?

A mailer has four options for the placement of an ancillary service endorsement. These endorsements are important because they provide additional information on the mailpiece, such as handling instructions or service requests, which can help ensure the correct processing and delivery of the mail.

The four specific placements for these endorsements include:

1. The upper right corner of the address side.

2. The lower left corner of the address side.

3. The lower right corner of the address side.

4. The back of the mailpiece.

Each placement option has specific guidelines to follow, but overall, having four different locations provides flexibility for mailers depending on their design or layout needs. Understanding these options is crucial for ensuring that endorsements are placed correctly to be easily seen and processed by postal services.
